Q: IPU + image scrolling [Linux]

I need to implement image scrolling under Linux on a imx535.

According to the " i.MX53 Multimedia Applications Processor Reference Manual", Update Of The Display Buffer:

"Automatic display of a changing image (animation) or moving image (scrolling) This

is implemented by reading frames (from a full plane buffer) with incremental offset"


Seems that is exactly what I need. I tried to research IPU driver located in $BUILD/linux/drivers/mxc/ipu*, but seems that current implementation of IPU driver and therefore user-space library does not support scrolling feature at all.

Does anybody dig into this field yet? I also tried to search IMX community - no results so far:(

Thanks for any info!
